PIPE-COUPLING.

Our invention consists in an improvement upon the slide coupling for which Letters Patent were granted to R. I. Falconer June 7th, 1853, described and represented as follows: Instead of making the male and female parts or sections of the coupling to draw, or in other words instead of making the coupling water tight by means of the oblique or wedge shaped form of the flanges of these two parts, we make the flanges straight so that the male partor sectiona will enter freely and leave some space between it and the face of the female section b. When the sections have been entered we insert between their flanges keys or wedges d, 01, so as to set up and tighten the sections 26,517, dated December 20, 1859.

The Falconer coupling requires a high fin ish to prevent leakage and also requiressome attention to securethe perfectimatching of f its two sections, so that their central open-, ings shall exactly correspond and leave no 1 breaksto resist the flow of water. By entering the sections first and matching them and 1 I a all such di culties are avoided and weare enabled to make a watertight joint with, rough castings or without anyfinish totthe Q faces of the two sections, while we have the 505, There are j then settin up by and .endwise movement full benefit of the side or slide coupling over what are called end couplings.
